Keeping a characters body part centered when creating animation cycle from poses?

in The Commons
If this has been discussed can somebody please post a link.
I am trying to create an animation cycle from a pose package, and would like to keep a characters body part centered to make it look more natural. To be more specific a ballet dance cycle and would like to keep the characters right toes in the same spot when changing poses. Something tells me this is a simple task, and maybe I'm not thinking far enough outside the box, but I'm getting frustrated. If anyone has any ideas could you please share.

I really don't know anything about animation so I'm not sure, but could this be helpful to you: https://www.daz3d.com/glue-to-floor-utility-for-genesis-8-females
Daz just posted a video about this exact thing a few days ago.
Thank you to both of you, that is exactly what I was looking for. I did not know Daz had posted such a video. I also wasn't aware of the tool you could buy to help do that. Again thank you this will help a bunch and relieve some of that frustration.
